COMPLETE Summary
The Distributed File System (DFS) implementation in Microsoft Windows XP SP2 and SP3 and Server 2003 SP2 does not properly validate fields in DFS responses, which allows remote DFS servers to execute arbitrary code via a crafted response, aka "DFS Memory Corruption Vulnerability."

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| description | The Distributed File System (DFS) implementation running on the remote Windows host has the following vulnerabilities: - The DFS client does not parse specially crafted DFS responses correctly, which could allow a remote, unauthenticated attacker to execute arbitrary code. (CVE-2011-1868) - The system does not properly handle specially crafted DFS referral responses, which could allow an unauthenticated, remote attacker to cause a denial of service. (CVE-2011-1869) |
